Answer:
No it is defined.
Step-by-step explanation:
-7 / 56
= -1/8 or -0.125
The small triangle and big triangle are similar - this means they have the same angles. So, if you know the ratio of a side of the big triangle (12) to a side of the small triangle inside it (4), you know the ratio of the other sides. In this case, the side ratio (small to big triangle) is 1/3. Thus, the missing side length is 18/3=6.

Nice, so
parabola equation is
4P(x-h)=(y-k)^2 (sideways parabola) or
4P(y-k)=(x-h)^2 (up and down parabola)
it is a vertical parabola since the focus is directly above the vertex
P is the distance from the vertex to the focus which is 3
it is positive since the focus is above it
4(3)(y-k)=(x-h)^2
(h,k) is the vertex
vertex is 0,0
4(3)(y-0)=(x-0)^2
12y=x^2
y=(x^2)/12
Ok so 1 centimeter equals 10 millimeters
So 18 centimeters equals 180 millimeters.
So the pencils were 180 millimeters each.
hope this helps!
Answer:
1). Surface area of the prism = 112 cm²
2). Area of the sphere = 615.8 cm²
Step-by-step explanation:
1). Surface area of the triangular prism = Area of the triangular bases + Area of three lateral (rectangular) sides
Area of a triangular base = 
= 
= 10.5 cm²
Area of a rectangle = Length × width
Area of the rectangular lateral sides = (3 × 5) + (8 × 5) + (7 × 5)
= 15 + 40 + 35
= 90 cm²
Surface area of the prism = (2 × 10.5) + 90
= 21 + 90
= 112 cm²
2). Surface area of the sphere = 4πr²
= 4π(7)²
= 615.75
≈ 615.8 cm²
